Forum: movies Subject: Some questions about the archive.org video-file derivation system

Good morning,

I have a question about the archive's video-derivation system.

I have noticed that, for instance, They Call It All-States has derived a "512Kb MPEG4" from the original MPEG2. I am fascinated by this process. How exactly have you set up the archive.org uploading system to automatically derive these files?

Regards,

mamtmultim

There are some details on the blog on the use of the ffmpeg utility to generate the derivatives:
